CAPRYLYL 2-GLYCERYL ASCORBATE.

Valuable CAS 1359731-61-5 / ANTIOXIDANT, HUMECTANT

An advanced, amphiphilic Vitamin C derivative engineered for superior stability and skin penetration. Unlike traditional L-Ascorbic Acid, this molecule is both water and oil-compatible, allowing it to target multiple skin layers to address pigmentation, acne, and aging simultaneously.

Summary

Antioxidant Brightening Agent Humectant Anti-Acne Support Collagen Booster

Science

Mechanism of Action

This molecule acts as a multi-stage pigment inhibitor by suppressing tyrosinase activity and blocking melanin transport to the skin's surface. It simultaneously functions as a potent antioxidant to scavenge reactive oxygen species (ROS), stimulates fibroblasts to increase Type I collagen synthesis, and provides antimicrobial benefits against P. acnes while the glyceryl moiety maintains cellular hydration.

Key findings

  1. 01 Clinical trials demonstrated that 0.1% concentration significantly improved post-inflammatory hyperpigmentation (PIH) and metal-allergy induced pigmentation within 1-5 months of twice-daily use.
  2. 02 Studies indicate efficacy as low as 0.01% for reducing acne-related redness and minor pigmentation.
  3. 03 Research shows a reduction in scalp irritation and itching through the inhibition of thromboxane A2 in keratinocytes.

0.01%

Due to its high potency, clinical efficacy is seen at very low levels (0.01%). This leads many brands to 'dust' the ingredient at minimal concentrations for marketing claims. For precision results in brightening and collagen support, we look for concentrations between 0.1% and 1%.
